1977 Maestro Parametric Filter Overdrive Fuzz

1977 Maestro Parametric Filter. Made in USA, serial number MPF2040. This amazing vintage effect pedal works as a filter and also as an Overdrive / Fuzz. We believe it was used on some Queens of the Stone Age stuff, to get you an idea what it could sound like. Missing the battery lid, happens often on these old Maestro pedals.
